IMPROVEMENT IN TOOL FOR CUTTING MOULDIN GS.

TO ALL WHOM IT MAY CONCERN:

Be it known that I, EDWIN C. AIIs'rIN, of the village of Monroe, in thecounty of Green, and State of Wiscousin, have invented a new and usefulTool for Cutting Rope or Screw Mouldings; and I hereby declare that thefollowing is a full, clear, and exact description of theconstruction andoperation of the same, reference being had to the annexed drawingsmaking a. part of this specification, in which- Figure 1 is alongitpdinal section.

FigurerZ, a top view.

Figure 3, a piece of moulding.

Figure 4, a cross-section.

Figure 5, a top view of one of the knives.

Figure 6, a reverse view of one of the knives.

Figure 7, a perspective view of one of the knives.

The nature and object of my invention consists in constructing a toolfor the manufacture of what is called rope or screw moulding, so thatthe moulding will be completed by once passing' Vthrough the tool,and'in constructing the knives or cutters with projecting points and areceding edge, so that a smooth cut against the grain of the'wood can beobtained, and brought to Or nea'r to the edgewithout splitting ormarring the wood.

To enable others skilled in the art to make and use my invention, Iproceed to describe its construction and operation. i I

The body or shaft A is made of wood or iron, as may be preferred, andcan be made whole -or in halves, and bolted together by the bolts d. Itis about eight inches long, and is provided with journals at-the ends,or a journal end belt or gear-wheel, as may be desired; or it may beconstructed so as to be used by hand. Through this shaft a hole orcircular cavity, B, is made longitudinally, of the size desired for themoulding. 0n each side of the shaftA I attach knives or cutters, C, ofwhich there are three or more, according tothe desired style ofmoulding; four will be found most convenient, and less than three cannotWell be used. The

knives orcutters are set at an angle of about forty-livel degrees withthe hole B, (a greater or less angle may be used i if desired and areadjustableby the slots I1 and bolts a. These knives are made V-shaped atthe cutting end, and are soconstructed that the cutting edge willregularly recede from the points c to the pointe.v The eect of this inuse is, that, as the tool or' the stick rotates,"the cutting will bedownwards, the upper portion of the wood being cut irst, and thus asmooth cut is made, and the wood is prevented from checking orsplitting. The points c are made to project slightlyover each side ofthe cutting edge, and are bevelled off on the under side. The object ofthis is also to prevent checking or splitting, particularly when cuttingbetween the cords partly cnt by the fron-t knives. The knives are soconstructed and attached that there is a pressure on the wood justforward and at the commencement of the cutting. By the use of theseknives I am enabled to cut a smooth rope or screw moulding, neatlyfinished as it comes fromA the machine. The sticks D before being passedthrough the tool are reduced to proper size by a chuck, placedimmediately in front of the tool or in a separate machine; and themoulding may 'be used whole as it comes from the machine, or may besplit and used in halves. It will be found best to place the knives onboth sides of the shaft A, as shown. The knives must be adapted in sizeto the moulding desired, and must be placed so that those ou one -sideof the shaft are somewhat in advance of those-on the opposite side, asshown.

Having thus -fully described my machine, what I claim as my invention,and ,desire to secure'byKLetters Patent, is

L-The knives C, constructed with the projections or bearings c, pressinguponv the surface of the Wood in advance of the cutting edge,substantially as and for the purposes specified.

2. The tool herein described for cutting ripe or screw moulding,constructed and operating substantially as described.
